Matthew Wilcox (Oracle) 4ee60ec156 include: remove pagemap.h from blkdev.h
My UEK-derived config has 1030 files depending on pagemap.h before this
change.  Afterwards, just 326 files need to be rebuilt when I touch
pagemap.h.  I think blkdev.h is probably included too widely, but
untangling that dependency is harder and this solves my problem.  x86
allmodconfig builds, but there may be implicit include problems on other
architectures.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
